110304 - if mailnews.headers.showUserAgent = true, Mozilla should show X-Mailer header if no User-Agent header found

Status: VERIFIED DUPLICATE of bug 65472

(SeaMonkey :: MailNews: Message Display, defect)

Description

[Tillmann Steinbrecher]

Hi,

if
user_pref("mailnews.headers.showUserAgent", true);

is set, Mozilla will display the "User-Agent" header. This is nice and works
fine. However, most other email programs (Eudora, The Bat, the various
incarnations of M$ Outlook, etc...) don't use the User-Agent header, but instead
"X-Mailer".

Examples:
X-Mailer: Microsoft Outlook, Build 10.0.2616
X-Mailer: QUALCOMM Windows Eudora Version 5.1
X-Mailer: The Bat! (v1.54/10) Educational
X-Mailer: MIME-tools 5.41 (Entity 5.404)
X-Mailer: AOL 6.0 for Windows DE sub 10504

Since the real purpose of this option is to be able to see which program was
used to write this mail, Mozilla should either display the User-Agent OR
X-Mailer header.

Personally I find this option VERY useful. It should have its own checkbox in
the Preferences. The X-Mailer tells a lot about an user and allows you to chose
your language appropriately - E.g., when replying to a technical question, I'd
use more simple terms when writing to someone using AOL WebMail then when
writing to someone using PINE on Solaris :-).

bye,
Till

Duplicate of "X-mailer in addition to User-Agent"

(has a patch which is out of date, has a strong "wontfix" sentiment)

Basically, X-mailer is obsolete and should be being phased out in favor of
User-Agent.
